To all whom it may concern.-

Be it known that I, ADoLPH SOMMER, a cit-izen of the United States, anda resident of Berkeley, in the county of Alameda and State ofCalifornia, have invented a new and usefulImprovement inNeutralizing'Sulphochlo- ,rinated Compounds, (for which I have ob-''tained Letters Pat-entas follows: in England- September 4, 1888, No.12,795; in Belgium IO September 4., 1888, N 0. 83,139, and in FranceSeptember 4, 1888, No. 192,770;) and I do hereby declare that thefollowing is an exact description of the invention, which will enableother chemists to perform the same operation.

When chloride ofi sulphur is mixed with organic substances (such as fatsand oils) there is generally more orless chlorhydric acid formed andabsorbed in themixture.

state is conducted into them or into a strong.

solution of the same, it, has been universally assumed that they areincapable of combining with this acid when itis presented in ,a highlydilute state but while. it is-I-true that they are incapable ofneutralizing-aqueoussolu tionsof hydrogen chloride, 1 find thatthey arewell able to completely neutralize anhy- 4o drou's substances of thecharacter-mentioned 'tionof one percent. of acid. f

, Of the numerous. compounds which belong 1 above, even when theycontain only a fracto the terpenes and olefines, and which may beuse'dfor the purpose herein described, I will only mention'those which, onaccount of their abundance and cheapness, are available for technicalpurposes. 0f the terpenes' the commercial oils of turpentine are generally the cheapest,and of theolefines I consider as the most availablepropylene, buty- The removal 1 20 of this acid I have previouslyeffected by the lene, beta-amylene, beta-hexylene, and some of theirisomeres and homologues. Generally it is not necessary that thesecompounds be pure. Any substance containing an a'ppreci able quantity ofthem, providedit be not otherwise objectionable in the preparation to beneutralized, may be employed for this purpose. Thus, instead ofemploying the pure'olefines, I use either a gas or a liquid obtained bythe destructive distillation ofi some carbonaceous material, such asbituminous shale, lignite, peat, resins, and fats. v

In order to enable the neutralizing agent to readily permeate the acidsubstance, the'65 latter, if it be a solid; is either by melting ordissolving brought to the liquid state, or is reduced by grinding orotherwise to .an evengrained coarse powder.

VVhen'a gas is chosen as the neutralizing 7o agent, it is simplyconducted in a slow and broken current into and through the acidsubstance until the escaping gas showsno trace of acidity, while in thecase of a liquid'agent I always take a somewhat larger quantitythan istheoretically necessary to neutralize the acid, incorporate the samethoroughly with the acid substance, and allow the mixture to stand forsome time. I t

The quantity of the-substance containing the olefine or terpene which istheoretically sufiicient for the neutralization. of the acid dependsupon the following factors: first, the kind of ole'fine or terpenepresent; second, the V richness of the substance in olefines or ter- S'penes; ,third, the degree of acidity of the preparation to beneutralized, and can for any I given'case be readily determined by-acompef tentchemist, The'compositions thus obtained may beenrirgo ployedfor the various purposeslfor which neutral sulphochlorinated. compoundsare. adapted, and in which the presence of the" unsaturated hydrocarbonsor of theineh'lorhydric-acid derivatives is not objectionable Of thepurposes for which they arethe'reforesuitable, I will mention theiremployment in the manufacture of paint-oils (Patent No. 396,774, ofJanuary 29, 1889;) in the manufacture of lubricants, (Serial No.286,795, filed 10obyrme September 29, 1888;) of water-proof leather,(Serial No.'233,044, filed by meMarch ing indig-rubben; w I
